Is the front anti sway bar on the XJ-S?
The common U.S. XJ-S has a front anti-sway bar only, and understeers accordingly. However, early models (prior to VIN 106452; 1979-1/2) came with a rear anti-sway bar as well.
Can you change the front bar on a Jaguar XJ?
These parts can be added to the later XJ-S, and were designed by Jaguar to provide balanced handling when used with the stock front bar. The radius arm assemblies must be replaced to provide attachment points for the anti-sway bar, or attachment points can be welded onto the existing radius arms.
What’s the difference between front and rear XJ-S suspension?
Because of differences in the leverage of the anti-sway bar linkage as well as in suspension geometry and center of gravity, a 1/2″ bar may be quite stiff on one car while a 1″ bar may be barely adequate on another. The common U.S. XJ-S has a front anti-sway bar only, and understeers accordingly.
What should I do to my JAG XJ suspension?
For those who wish to get serious about cornering, an excellent plan is to replace the 7/8″ front bar with a stiffer one, and to install a suitably heavy-duty item in the rear to match. “Sportspack” models come with a stiffer front anti-sway bar, and a rear anti-sway bar that is stiffer than the pre-1979-1/2 model described above.
